使用PHP连接到受密码保护的Web服务

Question

I am trying to connect to a Web Service which is password protected and I can't figure out what the Guid is for. I have a basic understanding of SOAP and will be using PHP's SoapClient.

The following was sent to me:

    Guid Login(string Username, string Password)

    string Add(Guid AccessKey, string CompanyCode, string CustomerNumber,
    string Address)

The above 'Add' is to add a user to the database after authentication. If anyone is familiar with SOAP and can help me with the Guid it will be highly appreciated.

Answer 1

After a long struggle I found that as michaJIS said it is a session ID and one lust get this when requesting with the username and password. This Session ID must then be used in all other requests.
